Mexican student creates an acoustic fire extinguisher to put out fire in seconds
A 16-year-old student built 'Vortex Tech,' an acoustic extinguisher emitting 30 sound pulses per second that extinguishes small fires in five to eight seconds.
Ángela Karime Venegas Hernández, a student at CETIS 78 in Altamira, Tamaulipas, built a device combining a 12-volt battery, a frequency generator, and a speaker emitting 30 pulses per second. The acoustic vibration displaces oxygen away from flames, putting out fires in five to eight seconds. She validated the approach in over 100 tests on wood, flammable liquids, cooking grease, and electronic equipment, with no pollution or residue. The project, named Vortex Tech, will be presented by the student as Mexico's entry at an international science fair.
- Device uses a 12-volt battery, frequency generator, and speaker pulsing 30 times per second.
- Extinguishes fires in wood, flammable liquids, grease, and electronics without leaving residue.
- Student will represent Mexico with Vortex Tech at an international fair.

Ángela Karime Venegas Hernández is 16 years old and has an idea no one else had.
She studies at CETIS 78 in Altamira, Tamaulipas, and one day decided to put out a candle without blowing, without water, without anything but sound. She assembled a device with a 12-volt battery, a frequency generator, and a speaker that emits 30 pulses per second. That vibration pushes oxygen away from the flames, and the fire simply goes out in five to eight seconds.
She tested it over and over, more than 100 times, until confirming that it also worked on wood, flammable liquids, cooking grease, and electronic equipment. It does not pollute, leave residue, or hurt the person using it. What began as a school experiment now has a name of its own, “Vortex Tech”, and is taking Ángela to represent Mexico at an international fair, where she will present her way of combating one of humanity’s oldest dangers to the world.
